Randomized Controlled Trial Clinical Trial
A randomized, prospective trial of adjuvant chemotherapy in adults with soft tissue sarcomas of the head and neck, breast, and trunk.
Since 1977, 31 patients were entered in a randomized, prospective study testing the efficacy of adjuvant chemotherapy after aggressive local treatment of high-grade sarcomas of the head, neck, breast, and trunk (excluding retroperitoneal sarcomas). All patients had complete resection of gross tumor and underwent postoperative radiotherapy (6000-6300 rads over 7-8 weeks). Seventeen patients received adjuvant chemotherapy consisting of doxorubicin (less than or equal to 550 mg/m2), cyclophosphamide (less than or equal to 5500 mg/m2), and methotrexate (less than or equal to 1000 mg/kg). ⋯ The subgroup of patients with sarcomas of the trunk (39 patients) demonstrated the greatest benefit from chemotherapy, with regard to disease-free survival (P less than or equal to 0.001). The most significant toxicity associated with chemotherapy was doxorubicin-induced cardiomyopathy, which resulted in clinically apparent congestive heart failure in five patients. Thus, the use of chemotherapy when combined with aggressive local measures appears to improve disease-free survival, but additional patients and longer follow-up are necessary to determine if improved overall survival will result.

A 30-year-old man presenting with watery diarrhea, hypokalemia, and hypochlorhydria (Verner-Morrison syndrome, WDHH syndrome) had raised plasma levels of vasoactive intestinal polypeptide (VIP), somatostatin (SRIF), calcitonin, and gastrin, as well as high urinary excretion of vanillylmandelic acid. A right adrenal pheochromocytoma was found and excised. ⋯ Postoperatively, the patient recovered from his symptoms and the plasma hormone levels returned to normal values. The clinical and histogenetic implications of this most unusual tumor of neural crest derivatives are discussed.

Fifteen patients with chronic malignant intractable pain were given epidural narcotics for periods of up to 280 days. The majority were treated at home. The patients self-administered the narcotics through an indwelling epidural catheter that had been tunneled and brought out onto the anterior abdominal wall. The results are presented together with the problems encountered.

A supportive family environment is thought to enhance the capacity of cancer patients to adapt to their illness and treatment. But families, like patients, vary in their ability to cope with the impact of a cancer diagnosis in a family member and in their ability to fulfill the patient's needs. Increased understanding of the interrelationships between the family's and patient's responses to illness is of fundamental importance to the care of the patient with cancer. ⋯ These data suggest a mutuality of psychological response between patients and their families. Supportive intervention for the patient or relative who manifests distress, therefore, should benefit both. Because patients and relatives involved with palliative treatment are most in need of psychological assistance, particular attention should be paid to this group, as is attempted in hospice care.

Actuarial progression-free survival rate at 5 years of a series of 34 patients with medulloblastoma treated by combined surgery, radiotherapy, and chemotherapy was 71%. No relapses were observed in 14 patients followed for more than 5 years. Treatment consisted of a short postoperative course of vincristine (VCR) and intrathecal (IT) methotrexate (MTX) followed by irradiation to the entire cranio spinal axis. ⋯ Failure occurred in nine patients: four had local recurrence, four dissemination within the central nervous system, and one widespread skeletal metastases. Poor prognostic factors such as presence of malignant cells in the cerebrospinal fluid, non-radical surgery, young age, and radiation doses less than 50 Gy to the tumor bed, did not adversely affect the outcome of patients in this series. Long-term sequelae from the treatment program could be observed in all patients, and in 58% they were severe enough to interfere with normal, active life.
